title: Theoretical specific capacitance based on charge storage mechanisms of conducting polymers: comment on 'Vertically oriented arrays of polyaniline nanorods and their super electrochemical properties'.
abstract: A recently claimed ultra high specific capacitance of 3407 F g(-1) for aligned polyaniline nanorods by the titled communication is shown to be contradictory to both the mechanism of charge storage in conducting polymers, and the experimental findings in other nanofibrils of polyaniline, and may thus stimulate debate.
